In demo 7.5, the whole level was remade. Mario starts in a special kind of Yoshi that has the ability to do everything that a normal yoshi with a Disco Shell in the mouth: he can fly and make the ground shake when he touches the ground, and he can shoot a unlimited amount of fireballs.

The first boss is Nova from the kirby series. Afterwards, Mario seemingly beats the level, but the Goal Point Question Sphere is fake and Marx takes Mario to a battle.

When Marx is beaten, Kirby appears and swallows Marx and then you have to battle Marx Kirby.
